So, in my superflat creative world.  Set to be all cherry blossom grove, I found a Eerie biome next to my base.  both of the nodes in the area were normal.  How did it get there and how do I get rid of it?  I already put down ethereal blooms.
I would post my screenshot but I don't know how to upload it.
Also, I am using the Direwolf20 Pack
